Abstract
Objectives Early diagnosis and treatment of inflammatory arthritis (IA) is essential to optimize disease control. We aimed to identify variables that distinguish IA from non-inflammatory arthropathy by performing a cross-sectional study of rheumatology referral letters and visit records. Further work describes time to assessment and documentation of variables within referral letters. Methods We reviewed rheumatology referral letters and new patient visits over a 6-month period. The diagnosis of IA was based on the clinical judgement of the assessing rheumatologist. IA diagnoses included RA, SpAs, unspecified IA, PMR, crystalline arthropathies and remitting seronegative symmetrical synovitis with pitting oedema. Univariate analysis was performed for each variable. Multivariable logistic regression was performed on statistically significant variables. Results Of 697 patients referred for arthralgia, 25.7% were diagnosed with IA. Variables predictive of IA included tenderness and swelling on examination and ≥1 h of morning stiffness. Increasing arthralgia duration, fatigue and brain fog were negative predictors. The median time from referral to IA diagnosis was 55 days and 20.7% of these patients were seen within 6 weeks. Among referral letters, documentation of arthralgia duration, morning stiffness or joint examination findings was uncommon (31%, 20.5% and 56.7%, respectively). Conclusion We identified positive and negative predictors of IA. Referral letters often missed key information required for the triaging process. Future efforts will be directed towards build a triaging tool to improve the referral quality and capture of those patients with IA who need earlier access to rheumatology care.

Abstract
C-reactive protein (CRP) is routinely assessed as a marker of systemic inflammation in rheumatoid arthritis (RA). However, it is also an immune regulator that plays an important role in inflammatory pathways associated with RA and promotes atherogenic effects. Comorbidities linked to systemic inflammation are common in RA, and CRP has been associated with the risk for cardiovascular disease, diabetes, metabolic syndrome, pulmonary diseases, and depression. The relationship between systemic inflammation, CRP, and comorbidities in RA is complex, and it is challenging to determine how changing CRP levels may affect the risk or progression of these comorbidities. We review the biological role of CRP in RA and its implications for disease activity and treatment response. We also discuss the impact of treatment on CRP levels and whether reducing systemic inflammation and inhibiting CRP-mediated inflammatory pathways may have an impact on conditions commonly comorbid with RA.

Abstract
OBJECTIVES To conduct a systematic review and longitudinal meta-analysis of early rheumatoid arthritis (RA) cohorts with long-term data on pain, fatigue or mental well-being. METHODS Searches using PUBMED, EMBASE and PyscInfo were performed to identify all early RA cohorts with longitudinal measures of pain, fatigue or mental well-being, along with clinical measures. Using longitudinal meta-analyses, the progression of each outcome over the first 60-months was estimated. Cohorts were stratified based on the median recruitment year to investigate secular trends in disease progression. RESULTS Of 7,319 papers identified, 75 met the inclusion criteria and 46 cohorts from 41 publications provided sufficient data on 18,046 patients for meta-analysis. The Disease Activity Scores (DAS28) and the Short-Form 36 (SF-36) Physical Component Score (PCS) indicated that post-2002 cohorts had statistically significant improvements over the first 60-months compared to pre-2002 cohorts, with standardised mean differences (SMD) of 0.86 (95% Confidence Intervals 0.34 to 1.37) and 0.76 (95% CI 0.25 to 1.27) respectively at month-60. However, post-2002 cohorts indicated statistically non-significant improvements in pain, fatigue, functional disability and SF-36 Mental Component Score (MCS) compared to pre-2002 cohorts, with SMD of 0.24 (95% CI -0.25 to 0.74), 0.38 (95% CI -0.11 to 0.88), 0.34 (95% CI -0.15-0.84) and -0.08 (95% CI -0.41 to 0.58) at month-60 respectively. CONCLUSIONS Recent cohorts indicate improved levels of disease activity and physical quality of life, however this has not translated into similar improvements in levels of pain, fatigue and functional disability by 60-months.

Abstract
BACKGROUND Joint hypermobility syndrome (JHS) is a heritable disorder associated with laxity and pain in multiple joints. Physiotherapy is the mainstay of treatment, but there is little research investigating its clinical effectiveness. OBJECTIVES To develop a comprehensive physiotherapy intervention for adults with JHS; to pilot the intervention; and to conduct a pilot randomised controlled trial (RCT) to determine the feasibility of conducting a future definitive RCT. DESIGN Patients' and health professionals' perspectives on physiotherapy for JHS were explored in focus groups (stage 1). A working group of patient research partners, clinicians and researchers used this information to develop the physiotherapy intervention. This was piloted and refined on the basis of patients' and physiotherapists' feedback (stage 2). A parallel two-arm pilot RCT compared 'advice' with 'advice and physiotherapy' (stage 3). Random allocation was via an automated randomisation service, devised specifically for the study. Owing to the nature of the interventions, it was not possible to blind clinicians or patients to treatment allocation. SETTING Stage 1 - focus groups were conducted in four UK locations. Stages 2 and 3 - piloting of the intervention and the pilot RCT were conducted in two UK secondary care NHS trusts. PARTICIPANTS Stage 1 - patient focus group participants (n = 25, three men) were aged > 18 years, had a JHS diagnosis and had received physiotherapy within the preceding 12 months. The health professional focus group participants (n = 16, three men; 14 physiotherapists, two podiatrists) had experience of managing JHS. Stage 2 - patient participants (n = 8) were aged > 18 years, had a JHS diagnosis and no other musculoskeletal conditions causing pain. Stage 3 - patient participants for the pilot RCT (n = 29) were as for stage 2 but the lower age limit was 16 years. INTERVENTION For the pilot RCT (stage 3) the advice intervention was a one-off session, supplemented by advice booklets. All participants could ask questions specific to their circumstances and receive tailored advice. Participants were randomly allocated to 'advice' (no further advice or physiotherapy) or 'advice and physiotherapy' (an additional six 30-minute sessions over 4 months). The physiotherapy intervention was supported by a patient handbook and was delivered on a one-to-one patient-therapist basis. It aimed to increase patients' physical activity through developing knowledge, understanding and skills to better manage their condition. MAIN OUTCOME MEASURES Data from patient and health professional focus groups formed the main outcome from stage 1. Patient and physiotherapist interview data also formed a major component of stages 2 and 3. The primary outcome in stage 3 related to the feasibility of a future definitive RCT [number of referrals, recruitment and retention rates, and an estimate of the value of information (VOI) of a future RCT]. Secondary outcomes included clinical measures (physical function, pain, global status, self-reported joint count, quality of life, exercise self-efficacy and adverse events) and resource use (to estimate cost-effectiveness). Outcomes were recorded at baseline, 4 months and 7 months. RESULTS Stage 1 - JHS is complex and unpredictable. Physiotherapists should take a long-term holistic approach rather than treating acutely painful joints in isolation. Stage 2 - a user-informed physiotherapy intervention was developed and evaluated positively. Stage 3 - recruitment to the pilot RCT was challenging, primarily because of a perceived lack of equipoise between advice and physiotherapy. The qualitative evaluation provided very clear guidance to inform a future RCT, including enhancement of the advice intervention. Some patients reported that the advice intervention was useful and the physiotherapy intervention was again evaluated very positively. The rate of return of questionnaires was low in the advice group but reasonable in the physiotherapy group. The physiotherapy intervention showed evidence of promise in terms of primary and secondary clinical outcomes. The advice arm experienced more adverse events. The VOI analysis indicated the potential for high value from a future RCT. Such a trial should form the basis of future research efforts. CONCLUSION A future definitive RCT of physiotherapy for JHS seems feasible, although the advice intervention should be made more robust to address perceived equipoise and subsequent attrition.

Abstract
OBJECTIVE To identify the disease activity trajectories during intensive triple disease modifying anti-rheumatic drug (DMARD) therapy over 3 years in rheumatoid arthritis (RA) patients and to evaluate the association with treatment persistence. METHODS Disease Activity Score in 28 joints, baseline risk factors and medication usage were obtained from a longitudinal observational cohort of early RA patients, most of whom were treated with combination DMARD therapy consisting of methotrexate, sulfasalazine and hydroxychloroquine. Persistence of each DMARD was defined as the duration of time from initiation to cessation. A group-based trajectory modelling technique was used to identify disease activity trajectories. RESULT Three disease activity trajectories (good [43.8%], moderate [39.7%] and poor [16.5%]) were identified in a cohort of 297 patients. Most baseline risk factors, medication usage, the rate of treatment persistence and the effect of persistence on disease activity differed among patients in each of the three trajectories. Although the rate of persistence was higher in the trajectory with a good outcome, the association with persistence was more pronounced among patients who were in the poor outcome trajectory. Persistence with at least two or all three baseline DMARDs was associated with a decrease in disease activity to a broadly similar degree in all trajectories. CONCLUSION After correction for other baseline prognostic factors, persistence with initial DMARDs contributes to heterogeneity in disease activity trajectory and there was an association between persistence with initial DMARD therapy and lower long-term disease activity.

Abstract
OBJECTIVE To identify baseline prognostic indicators of disability at 1 year within a contemporary early inflammatory arthritis inception cohort and then develop a clinically useful tool to support early patient education and decision-making. METHODS The Scottish Early Rheumatoid Arthritis (SERA) inception cohort is a multicenter, prospective study of patients with newly presenting RA or undifferentiated arthritis. SERA data were analyzed to determine baseline predictors of disability (defined as a Health Assessment Questionnaire [HAQ] score of ≥1) at 1 year. Clinical and psychosocial baseline exposures were entered into a forward stepwise logistic regression model. The model was externally validated using newly accrued SERA data and subsequently converted into a prediction tool. RESULTS Of the 578 participants (64.5% female), 36.7% (n = 212) reported functional disability at 1 year. Functional disability was independently predicted by baseline disability (odds ratio [OR] 2.67 [95% confidence interval (95% CI) 1.98, 3.59]), depression (OR 2.52 [95% CI 1.18, 5.37]), anxiety (OR 2.37 [95% CI 1.33, 4.21]), being in paid employment with absenteeism during the last week (OR 1.19 [95% CI 0.63, 2.23]), not being in paid employment (OR 2.36 [95% CI 1.38, 4.03]), and being overweight (OR 1.61 [95% CI 1.04, 2.50]). External validation (using 113 newly acquired patients) evidenced good discriminative performance with a C statistic of 0.74, and the calibration slope showed no evidence of model overfit (P = 0.31). CONCLUSION In the context of modern early inflammatory arthritis treatment paradigms, predictors of disability at 1 year appear to be dominated by psychosocial rather than more traditional clinical measures. This indicates the potential benefit of early access to nonpharmacologic interventions targeting key psychosocial factors, such as mental health and work disability.

Abstract
Self-report accounts of functional ability are important for clinicians to gain insight into individuals’ perspectives of the personal impact of injury or disease. This short report describes a study of self-report upper limb ability using the Disability of the Arm, Shoulder and Hand (DASH) questionnaire in a sample of people with early rheumatoid arthritis. The DASH is a reliable and valid tool for use within rheumatology. The most difficult upper limb tasks to complete were reported to be activities that required sustained force and power, followed by tasks that required fine finger movements and prehension tasks. The DASH questionnaire proved to be an outcome measure that discriminated well between different levels of reported functional upper limb ability; it was reported to be easy to complete by patients, and was straightforward and quick to score. The compact summary score makes it a useful clinical and research tool and one that can be recommended in an early rheumatoid arthritis population.

Abstract
OBJECTIVES We aimed to investigate the frequency of moderate-to-severe sleep apnea syndrome (SAS) that possibly influences long-term prognosis in patients with rheumatoid arthritis (RA), and to analyze the risk factors for this group. METHODS We examined respiratory disturbance index (RDI) by polysomnography in 62 hospitalized RA patients. Risk factors of moderate-to-severe SAS (RDI ≥20) were analyzed using a multivariate logistic regression analysis. RESULTS RA was complicated by moderate-to-severe SAS in 13/62 (20.9%) cases. The highest stage of temporomandibular joint abnormality (TMJA) and a high value of health assessment questionnaire-disability index (HAQ-DI) were significant risk factors, according to the results of the multivariate logistic regression analysis (p < 0.0001 and p = 0.010, respectively). Contrary to these results, RDI was not related to the disease activity indexes of RA and other clinical characteristics. CONCLUSION We clarified that the highest TMJA stage and a high value of HAQ-DI are novel important risk factors for moderate-to-severe SAS in RA patients.

Abstract
OBJECTIVES To investigate the effect of bilateral and unilateral joint disease on the Modified Health Assessment Questionnaire (MHAQ) scores and the differences in joint weighting in rheumatoid arthritis patients. METHODS A total of 9212 subjects from the Japanese nationwide cohort database NinJa, 2011, were analyzed. The presence or absence of disease in each joint, including swelling and/or tenderness, was investigated. The correlations between bilateral and unilateral disease in each joint and MHAQ scores were investigated using multivariable logistic regression analysis. RESULTS The patients' mean age and disease duration was 63.2 and 12.2 years, respectively. The Disease Activity Score-28 was 3.3. The odds ratios of physical impairment according to the MHAQ using multivariable logistic regression models for bilateral and unilateral joints, respectively, were: shoulder, 4.0 and 1.8; elbow, 2.6 and 1.8; wrist, 1.9 and 1.5; hip, 1.7 and 3.0; knee, 2.6 and 1.9; ankle, 2.3 and 2.0, finger, 1.4 and 1.2; and toe, 1.0 and 1.1. The shoulder, elbow, wrist, knee, and ankle had a significant effect on physical impairment. CONCLUSIONS The MHAQ score was significantly affected by shoulder, elbow, wrist, knee, and ankle joint disease. Furthermore, bilateral disease tended to have a greater effect on physical impairment than unilateral disease.

Abstract
OBJECTIVE Genetic variants affect both the development and severity of rheumatoid arthritis (RA). Recent studies have expanded the number of RA susceptibility variants. We tested the hypothesis that these associated with disease severity in a clinical trial cohort of patients with early, active RA. METHODS We evaluated 524 patients with RA enrolled in the Combination Anti-Rheumatic Drugs in Early RA (CARDERA) trials. We tested validated susceptibility variants - 69 single-nucleotide polymorphisms (SNP), 15 HLA-DRB1 alleles, and amino acid polymorphisms in 6 HLA molecule positions - for their associations with progression in Larsen scoring, 28-joint Disease Activity Scores, and Health Assessment Questionnaire (HAQ) scores over 2 years using linear mixed-effects and latent growth curve models. RESULTS HLA variants were associated with joint destruction. The *04:01 SNP (rs660895, p = 0.0003), *04:01 allele (p = 0.0002), and HLA-DRβ1 amino acids histidine at position 13 (p = 0.0005) and valine at position 11 (p = 0.0012) significantly associated with radiological progression. This association was only significant in anticitrullinated protein antibody (ACPA)-positive patients, suggesting that while their effects were not mediated by ACPA, they only predicted joint damage in ACPA-positive RA. Non-HLA variants did not associate with radiograph damage (assessed individually and cumulatively as a weighted genetic risk score). Two SNP - rs11889341 (STAT4, p = 0.0001) and rs653178 (SH2B3-PTPN11, p = 0.0004) - associated with HAQ scores over 6-24 months. CONCLUSION HLA susceptibility variants play an important role in determining radiological progression in early, active ACPA-positive RA. Genome-wide and HLA-wide analyses across large populations are required to better characterize the genetic architecture of radiological progression in RA.

Abstract
OBJECTIVE To explore the contributions from and interactions between articular swelling and damage, psychosocial factors, and body composition characteristics on walking speed in rheumatoid arthritis (RA). METHODS RA patients underwent the timed 400-meter long-corridor walk. Demographics, self-reported levels of depressive symptoms and fatigue, RA characteristics, and body composition (using whole-body dual X-ray absorptiometry, and abdominal and thigh computed tomography) were assessed and their associations with walking speed explored. RESULTS A total of 132 RA patients had data for the 400-meter walk, among whom 107 (81%) completed the full 400 meters. Significant multivariable indicators of slower walking speed were older age, higher depression scores, higher reported pain and fatigue, higher swollen and replaced joint counts, higher cumulative prednisone exposure, nontreatment with disease-modifying antirheumatic drugs, and worse body composition. These features accounted for 60% of the modeled variability in walking speed. Among specific articular features, slower walking speed was primarily correlated with large/medium lower-extremity joint involvement. However, these articular features accounted for only 21% of the explainable variability in walking speed. Having any relevant articular characteristic was associated with a 20% lower walking speed among those with worse body composition (P < 0.001), compared with only a 6% lower speed among those with better body composition (P = 0.010 for interaction). CONCLUSION Psychosocial factors and body composition are potentially reversible contributors to walking speed in RA. Relative to articular disease activity and damage, nonarticular indicators were collectively more potent indicators of an individual's mobility limitations.

Abstract
BACKGROUND Health care quality problems are reflected in the underuse, overuse, and misuse of health care services. There is evidence suggesting that the quality of rheumatoid arthritis (RA) patient care is suboptimal, which has spurred the development of a number of systematic quality improvement metrics. OBJECTIVE To investigate a quality process measurement set in a sample of commercially insured RA patients. METHODS Medical, pharmacy, and laboratory claims for members with an RA diagnosis (ICD-9-CM 714.x) during calendar years 2008 through 2012 were extracted from the Optum Clinformatics Data Mart database. Eight process quality measures focused on RA patient response and tolerance to therapy were examined in the claims database. Measures were calculated for individual calendar years from 2009 to 2012, inclusive. RESULTS The majority of adult RA patients received at least 1 prescription for a disease-modifying antirheumatic drug (DMARD) across the 4 measurement years: range = 78.5%-81.6%. Erythrocyte sedimentation rate and C-reactive protein testing were also evident in the majority of the sample, with 67.1%-72.2% of newly diagnosed RA patients receiving baseline testing, and 56.0%-58.7% of existing RA patients receiving annual testing. Among methotrexate users, liver function tests were performed in 74.5%-75.7% of treated patients, serum creatinine tests in 70.1%-72.6% of patients, and complete blood count tests in 74.5%-76.0% of patients. Additionally, most patients initiating a new DMARD had a claim for a baseline serum creatinine test (68.0%-70.3%) and baseline liver function test (69.3%-71.0%). CONCLUSIONS Findings suggest that a majority of RA patients are attaining patient quality process measures, although a considerable proportion of patients (approximately 25%) may be receiving suboptimal care. Further studies are warranted to understand whether attainment of these measures translates into better outcomes.

Clinical disease activity and acute phase reactant levels are discordant among patients with active rheumatoid arthritis: acute phase reactant levels contribute separately to predicting outcome at one year. Arthritis Res Ther 2014; 16:R40. [PMID: 24485007 PMCID: PMC3978994 DOI: 10.1186/ar4469] [Citation(s) in RCA: 80] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/09/2013] [Accepted: 01/24/2014] [Indexed: 11/25/2022] Open
Abstract
Introduction Clinical trials of new treatments for rheumatoid arthritis (RA) typically require subjects to have an elevated acute phase reactant (APR), in addition to tender and swollen joints. However, despite the elevation of individual components of the Clinical Disease Activity Index (CDAI) (tender and swollen joint counts and patient and physician global assessment), some patients with active RA may have normal erythrocyte sedimentation rate (ESR) and/or C-reactive protein (CRP) levels and thus fail to meet entry criteria for clinical trials. We assessed the relationship between CDAI and APRs in the Consortium of Rheumatology Researchers of North America (CORRONA) registry by comparing baseline characteristics and one-year clinical outcomes of patients with active RA, grouped by baseline APR levels. Methods This was an observational study of 9,135 RA patients who had both ESR and CRP drawn and a visit at which CDAI was >2.8 (not in remission). Results Of 9,135 patients with active RA, 58% had neither elevated ESR nor CRP; only 16% had both elevated ESR and CRP and 26% had either ESR or CRP elevated. Among the 4,228 patients who had a one-year follow-up visit, both baseline and one-year follow-up modified Health Assessment Questionnaire (mHAQ) and CDAI scores were lowest for patients with active RA but with neither APR elevated; both mHAQ and CDAI scores increased sequentially with the increase in number of elevated APR levels at baseline. Each individual component of the CDAI followed the same trend, both at baseline and at one-year follow-up. The magnitude of improvement in both CDAI and mHAQ scores at one year was associated positively with the number of APRs elevated at baseline. Conclusions In a large United States registry of RA patients, APR levels often do not correlate with disease activity as measured by joint counts and global assessments. These data strongly suggest that it is appropriate to obtain both ESR and CRP from RA patients at the initial visit. Requiring an elevation in APR levels as a criterion for inclusion of RA patients in studies of experimental agents may exclude some patients with active disease.

Abstract
BACKGROUND Arthritis is the most common cause of disability among US adults. Few studies have comprehensively examined factors associated with disability in this population. OBJECTIVE To investigate the relationship between a number of disease and non-disease related factors and disability in sample of adults with self-reported doctor-diagnosed arthritis. METHODS Participants (n = 396) taking part in a randomized controlled trial of arthritis self-management completed a comprehensive survey assessing a number of demographic, arthritis-specific, health-related, behavioral, and psychological variables at baseline. Disability, as measured by the Health Assessment Questionnaire (HAQ), was also measured. Hierarchical regression models examined the independent associations between blocks of variables and disability. RESULTS Demographic variables (R(2) = 0.13), arthritis-specific demographics (i.e., type, medication use; ΔR(2) = 0.16), physical health-related variables (ΔR(2) = 0.06), arthritis-specific symptoms (ΔR(2) = 0.12), health behaviors (ΔR(2) = 0.00), and psychological variables (ΔR(2) = 0.03) explained 50% of the variance in disability score (R(2) = 0.50). With the exception of health behaviors, the addition of each block of variables significantly improved the model, explaining additional variance in HAQ scores (p < 0.0001). In the final model, older age, less than a high school education, rheumatoid arthritis, greater arthritis duration, taking steroids, taking narcotics, greater pain, greater stiffness, greater depressive symptoms, and lower arthritis self-efficacy were associated with greater disability whereas male gender, fibromyalgia, and excellent/very good health were associated with less disability. CONCLUSIONS A number of disease and non-disease related variables were associated with disability. These findings suggest that disability in adults with arthritis may be a complicated phenomenon; such complexity may make decreasing disability in this population challenging.

Abstract
OBJECTIVE Our objective was to describe characteristics of Canadian patients with early arthritis and examine differences between those fulfilling 1987 and 2010 rheumatoid arthritis (RA) classification criteria. METHODS The Canadian Early Arthritis Cohort (CATCH) is a national, multicenter, observational, prospective cohort of patients with early inflammatory arthritis, receiving usual care, recruited since 2007. Inclusion criteria include age > 16 years; symptom duration 6-52 weeks; swelling of ≥ 2 joints or ≥ 1 metacarpophalangeal/proximal interphalangeal joint; and 1 of rheumatoid factor ≥ 20 IU, positive anticitrullinated protein antibodies (ACPA), morning stiffness ≥ 45 min, response to nonsteroidal antiinflammatory drug, or positive metatarsophalangeal joint squeeze test. Data from patients enrolled to March 15, 2011, were analyzed. RESULTS In total, 1450 patients met the eligibility criteria (1187 were followed). At baseline, mean age was 53 ± 15 years, symptom duration was 6.1 ± 3.2 months, Disease Activity Score (DAS28) was 4.9 ± 1.6, Health Assessment Questionnaire-Disability Index was 1.0 ± 0.7. Forty-one percent (n = 450) of patients had moderate (3.2 < DAS28 ≤ 5.1) and 46% (n = 505) had high (DAS28 > 5.1) disease activity; 28% of those with baseline radiographs (n = 250/908) had radiographic evidence of erosions. ACPA status was available for 70% (n = 831) of patients; 55% (n = 453) tested positive. Sixty percent (n = 718) of patients were treated with methotrexate (MTX) initially. Of 612 patients without erosions, 63% and 83% fulfilled 1987 and 2010 RA classification criteria, respectively. Seventy-three percent (n = 166) of those who did not fulfill 1987 criteria were newly identified by the 2010 criteria. These patients had less severe disease and more were MTX-naive compared to those satisfying the 1987 criteria. Forty-seven percent of all patients achieved remission at 1 year. CONCLUSION Patients with early RA present with moderate high disease activity; < 50% achieve remission at 1 year, despite MTX treatment in the majority. The 2010 RA classification criteria identify more patients with RA who would previously have been designated as having undifferentiated disease. However, these patients have lower disease activity at the time of identification.

Effects of long-term corticosteroid usage on functional disability in patients with early rheumatoid arthritis, regardless of controlled disease activity. Rheumatol Int 2010; 32:749-57. [PMID: 21161535 DOI: 10.1007/s00296-010-1638-4] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/01/2010] [Accepted: 11/14/2010] [Indexed: 10/18/2022]
Abstract
We investigated the effect of long-term corticosteroid usage in suppressing the progression of functional disability in patients with early rheumatoid arthritis (RA). We studied 3,982 RA patients, who had continuous enrollment for at least 3 years, among 9,132 RA patients enrolled in an observational cohort study, IORRA, in Tokyo, Japan, from 2000 to 2007. The DAS28 and Japanese version of Health Assessment Questionnaire (J-HAQ) scores were collected at 6-month intervals (each phase). Among these patients, those with DAS28 values under 3.2 in all phases and RA disease duration under 2 years at study entry were selected as "early RA patients with well-controlled disease". These patients were further classified into 3 groups based on average months of steroid usage per year: Non-users, Medium-users, and Frequent-users. Multiple linear regression analysis was used to study the relationship between steroid usage and the final J-HAQ scores. Among the 3,982 patients, 109 had DAS28 values under 3.2 in all the phases and were selected as study cohort. The average Final J-HAQ in Non-user (N = 64), in Medium-user (N = 25), in Frequent-user group (N = 20) was 0.04, 0.06, and 0.33, respectively. Multiple linear regression analysis after adjusting for all potential covariates confirmed that frequent steroid usage was the most significant factor associated with higher final J-HAQ scores (P < 0.05). Frequent steroid usage was associated with significantly higher final J-HAQ scores in early RA patients, even though their disease was managed efficiently by maintaining the DAS28 values under 3.2 over a long-term period.

Abstract
Introduction The aim of our study was to investigate the presence of disease activity in the metatarsophalangeal (MTP) joints of the forefoot in rheumatoid arthritis (RA) patients in remission according to the Disease Activity Score based on 28 joints (DAS28) remission criterion. Methods A total of 848 patients with recent-onset RA were included from 1995 through 2007. The DAS28 and pain and swelling of the MTP joints were assessed annually. The data were analyzed using descriptive techniques. Results On average, 35% of the patients fulfilled the remission criterion of DAS28 <2.6 during the first eight years of RA. On average, 29% of these patients had at least one painful MTP joint and, on average, 31% had at least one swollen MTP joint during follow-up. Forty percent, on average, had at least one involved MTP joint (pain and/or swelling). Conclusions Painful and/or swollen MTP joints were detected in a substantial proportion of patients classified as being in remission. Therefore, examination of the foot joints - irrespective of the patient's state of remission - seems indicated in order to provide optimal foot care.

Abstract
Linkage studies have identified the human leukocyte antigen (HLA)-DRB1 as a putative rheumatoid arthritis (RA) susceptibility locus (SL). Nevertheless, it was estimated that its contribution was partial, suggesting that other non-HLA genes may play a role in RA susceptibility. To test this hypothesis, we conducted microarray transcription profiling of peripheral blood mononuclear cells in 15 RA patients and analyzed the data, using bioinformatics programs (significance analysis of microarrays method and GeneNetwork), which allowed us to determine the differentially expressed genes and to reconstruct transcriptional networks. The patients were grouped according to disease features or treatment with tumor necrosis factor blocker. Transcriptional networks that were reconstructed allowed us to identify the interactions occurring between RA SL and other genes, for example, HLA-DRB1 interacting with FNDC3A (fibronectin type III domain containing 3A). Given that fibronectin fragments can stimulate mediators of matrix and cartilage destruction in RA, this interaction is of special interest and may contribute to a clearer understanding of the functional role of HLA-DRB1 in RA pathogenesis.

Abstract
Several advances have been made in the understanding of the pathogenesis, as well as in the clinical evaluation and treatment, of early inflammatory arthritis. The presence of anti-citrullinated protein antibodies (ACPAs) has emerged as a major new biomarker for use in clinical practice. The presence of ACPAs can be used to divide patients with early arthritis into subsets that are phenotypically similar but have varying pathogenetic and prognostic features. Although the detection of ACPAs is a major development in the diagnosis and prognosis of rheumatoid arthritis (RA), prediction of the outcome of arthritis at the individual level can still be much improved. For patients diagnosed with RA, and who have active polyarthritis, treatment is not dependent on the assessment of prognostic factors, as these patients are best treated with combination therapy; over 40% of these patients achieve remission with such treatment. In patients who present with oligoarthritis, however, management should be based on the assessment of prognostic factors. The success of early treatment of inflammatory arthritis and the recognition of a measurable preclinical phase of RA offer hope that treating the disease before it becomes clinically active might be possible.

Abstract
INTRODUCTION Rheumatoid arthritis is an inflammatory chronic disease that affects 0.5-1% of the population, many of whom develop disease as working-age adults. MATERIAL AND METHODS The aim of examination was to estimate functional disability in patients with rheumatoid arthritis and relationship between radiological damage, disease duration, disease activity, functional disability. The examination involved 60 patients with rheumatoid arthritis, aged (53.92 +/- 7.06) of both genders (48 female, 12 male). The following variables were assessed at one time point: swollen and tender joint count, visual analogue scale for pain, erythrocite sedimentation rate, health assessment questionnaire (HAQ) score, anatomical stage and functional class according to Stenbrocker's criteria. Disease activity was expressed as 28 joint disease activity score (DAS28). Correlations were calculated by Spearman's coefficient of correlation. RESULTS In our study 82% of the patients had II and III anatomical stage and 80% of the patients had II and III functional class according to Steinbrocker's criteria. The median HAQ score was 1.25 +/- 0.70, and the median DAS28 was 5.74 +/- 0.98. Poor functional status was observed in 37 (61.66%) of the patients with an HAQ score of = 2. Functional disability in patients with rheumatoid arthritis was most strongly related to the presence of pain (rs=0.338, p<0.01) and to a lesser extent to anatomical and functional stage, disease duration, disease activity. DISCUSSION AND CONCLUSION The results of the study show that functional disability significantly correlated with subjective pain score (rs=0.338, p<0.01). We observed strong correlation between functional disability presented by HAQ score and pain but no significant correlation with other common clinical variables used for rheumatoid arthritis patients evaluation such as disease duration, disease activity, radiological damage.

Abstract
OBJECTIVE To evaluate the prevalence and 8-year course of forefoot impairments and walking disability in patients with rheumatoid arthritis (RA). METHODS A total of 848 patients with recent-onset RA from 1995 through the present were included. The patients were assessed annually. Pain and swelling of the metatarsophalangeal (MTP) joints, erosions and joint space narrowing of the MTP joints and first interphalangeal joints, and the Health Assessment Questionnaire walking subscale were analyzed using descriptive and correlational techniques. RESULTS Pain and swelling of > or = 1 MTP joint was present in 70% of patients at baseline, decreasing to approximately 40-50% after 2 years. The forefoot erosion score was > or = 1 in 19% of the patients at baseline, and the prevalence of forefoot erosion increased to approximately 60% after 8 years, during which the mean forefoot erosion score increased from 1.3 to 7.9. At least mild walking disability was present in 57% of patients at baseline, stabilizing at approximately 40% after 1 year. CONCLUSION The prevalence rates for pain and swelling of the MTP joints and walking disability are initially high and then stabilize, but the prevalence and severity of forefoot joint damage increase during an 8-year course of RA. The findings of this study quantitatively emphasize the importance of forefoot involvement in patients with RA.

Abstract
This study aimed to evaluate the association between the differential gene expression profiling of peripheral blood mononuclear cells of rheumatoid arthritis patients with their immunogenetic (human leucocyte antigen shared-epitope, HLA-SE), autoimmune response [anti-cyclic citrullinated peptide (CCP) antibodies], disease activity score (DAS-28) and treatment (disease-modifying antirheumatic drugs and tumour necrosis factor blocker) features. Total RNA samples were copied into Cy3-labelled complementary DNA probes, hybridized onto a glass slide microarray containing 4500 human IMAGE complementary DNA target sequences. The Cy3-monocolour microarray images from patients were quantified and normalized. Analysis of the data using the significance analysis of microarrays algorithm together with a Venn diagram allowed the identification of shared and of exclusively modulated genes, according to patient features. Thirteen genes were exclusively associated with the presence of HLA-SE alleles, whose major biological function was related to signal transduction, phosphorylation and apoptosis. Ninety-one genes were associated with disease activity, being involved in signal transduction, apoptosis, response to stress and DNA damage. One hundred and one genes were associated with the presence of anti-CCP antibodies, being involved in signal transduction, cell proliferation and apoptosis. Twenty-eight genes were associated with tumour necrosis factor blocker treatment, being involved in intracellular signalling cascade, phosphorylation and protein transport. Some of these genes had been previously associated with rheumatoid arthritis pathogenesis, whereas others were unveiled for future research.

Abstract
Objective: To determine the efficacy and safety of etanercept and etanercept plus sulfasalazine versus sulfasalazine in patients with rheumatoid arthritis (RA) despite sulfasalazine therapy. Methods: Patients were randomly assigned to etanercept (25 mg twice weekly; sulfasalazine was discontinued at baseline), etanercept plus sulfasalazine (unchanged regimen of 2–3 g/day) or sulfasalazine in a double-blind, randomised, 2-year study in adult patients with active RA despite sulfasalazine therapy. Efficacy was assessed using the American College of Rheumatology criteria, disease activity scores (DAS) and patient-reported outcomes (PRO). Results: Demographic variables and baseline disease characteristics were comparable among treatment groups; mean DAS 5.1, 5.2 and 5.1 for etanercept (n = 103), etanercept plus sulfasalazine (n = 101) and sulfasalazine (n = 50), respectively. Withdrawal due to lack of efficacy was highest with sulfasalazine (26 (52%) vs 6 (6%) for either etanercept group, p<0.001). Patients receiving etanercept or etanercept plus sulfasalazine had a more rapid initial response, which was sustained at 2 years, than those receiving sulfasalazine: mean DAS 2.8, 2.5 versus 4.5, respectively (p<0.05); ACR 20 response was achieved by 67%, 77% versus 34% of patients, respectively (p<0.01) Overall, PRO followed a similar pattern; a clinically significant improvement in health assessment questionnaire was achieved by 76%, 78% versus 40% of patients, respectively (p<0.01). Commonly reported adverse events occurring in the etanercept groups were injection site reactions and pharyngitis/laryngitis (p<0.01). Conclusion: Etanercept and etanercept plus sulfasalazine are efficacious for the long-term management of patients with RA. The addition of etanercept or substitution with etanercept should be considered as treatment options for patients not adequately responding to sulfasalazine.

Abstract
To determine factors associated with functional disability in patients with rheumatoid arthritis (RA). A total of 100 RA patients were reviewed retrospectively. Multiple regression analysis was used to investigate associations between the dependent variable (health assessment questionnaire) and independent variables (age, disease duration, hand grip strength values, VAS and DAS-28 scores). Main factors associated with functional disability were disease activity score as reflected in a high score on the DAS-28 (r=0.68, p<0.001) and disease duration (r=0.23, p<0.05). Increased age, decreased grip strength and high pain level were associated with lower functional ability, but none of these was a predictor of disability in the regression model. The results indicate that age, disease duration, disease activity, pain intensity and hand grip strength are related to physical disability in patients with RA. However, only disease activity has an impact on physical function. Thus, treatment of RA patients should focus on early inhibition of disease activity in order to achieve a good functional outcome.

Abstract
PURPOSE To explore the role of distress and social support as modifiers of functional disability in rheumatoid arthritis (RA). We hypothesized that: (a) higher inflammatory activity, more joint tenderness and more pain lead to more disability, and (b) that more distress and less social support lead to more disability and accelerate the disablement process by moderating the effects of inflammatory activity, joint tenderness and pain. METHODS The study is a Dutch extension of the European Research on Incapacitating Diseases and Social Support (EURIDISS) which started with 292 patients. After five waves of data collection 129 still participated. Correlational and hierarchical regression analyses were performed. RESULTS In short-term RA, 68% of the variance in disability could be explained primarily by mean disability over the prior years. Other important predictors were inflammatory activity and pain. In long-term RA, 56% of the variance in disability could be explained primarily by mean disability over the prior years. Other important predictors were joint tenderness and pain. No clear moderator effects of distress and social support were found in short-term or long-term RA. CONCLUSIONS The results confirm the main pathway from pathology to disability in short-term and long-term RA, but do not provide support for the influence of distress and social support on the disablement process.

Abstract
Rheumatoid arthritis (RA) is a chronic, immune-mediated inflammatory disease characterised by inflammation resulting in structural joint damage and functional disability. Tumour necrosis factor-alpha (TNFalpha) is a pivotal mediator and driver of inflammation in RA. Inflammation is closely related to the production of C-reactive protein (CRP), and a close correlation exists between serum CRP and TNFalpha levels. CRP levels are therefore a convenient, objective biomarker of disease activity. CRP correlates closely with changes in inflammation/disease activity, radiological damage and progression and functional disability. Identification of TNFalpha as a driver of RA progression has led to the introduction of TNFalpha-blocking agents and, subsequently, improvement of disease management. TNFalpha-blocking agents provide rapid, profound and sustained suppression of disease activity in correspondence with a marked reduction in CRP levels. A reduction in CRP level correlates closely with the positive clinical response to TNFalpha-blocking therapy. Thus, CRP levels can be used to predict, assess and monitor response to treatment with TNFalpha-blocking agents, and may be helpful in determining the optimal TNFalpha-blocker dosage. Given the close correlation between inflammation and disease progression and the relation between inflammation and CRP, the latter, if used effectively in clinical practice, may be means to identify patients likely to progress rapidly and who require intensive anti-TNFalpha therapy. The purpose of this review is to identify how CRP levels may be useful for monitoring the effect of therapy on halting disease progression and why monitoring CRP levels at baseline and after treatment should become a routine part of clinical practice.

Abstract
Rheumatoid arthritis (RA) is a systemic autoimmune disease of unknown etiology, characterized by chronic joint inflammation that often leads to joint destruction. Diagnosis of RA is currently based on the revised classification criteria of the American College of Rheumatology (ACR); however, it remains imprecise, especially early in the course of disease. Rheumatoid factor (RF) has been widely used in clinical practice as a useful serological marker for diagnosis of RA. Although RF is the only serological test in the criteria of the ACR, its specificity is limited since RF can be also detected in other rheumatic diseases. Because the current therapeutic strategies in RA employ increasingly aggressive regimens from early stage of the disease, more specific serological markers than RF are desirable. Recently, anti-cyclic citrullinated peptide (anti-CCP) antibodies have attracted attention as a useful marker for the diagnosis of RA with high specificity. In addition to the diagnostic properties, anti-CCP antibodies showed to be a good prognostic marker for joint destructions. In this review, we will explain about the clinical usefulness of anti-CCP antibodies for the daily practice of RA.

Abstract
This article reviews radiographic data from six cohorts of patients with early inflammatory arthritis. Of the patients, 8% to 15% had erosive disease at the first encounter with the rheumatologist. Classic scoring methods were applied to quantify damage, but baseline damage was low in early inflammatory arthritis. Yearly progression in damage score was assessed only in patients with high suspicion of rheumatoid arthritis at baseline or who had a final diagnosis of rheumatoid arthritis at follow-up and varied between 0.5% and 1.7% of the maximal damage of the scoring method per year. The large number of patients with zero values for erosions and lower progression rates will influence sample sizes in clinical trials in early inflammatory arthritis when including radiographic change as an outcome.

Abstract
There are a number of theoretical frameworks that attempt to explain how individuals may adjust to threats to health and serious physical illness. The three major paradigms that attempt to organize key components of health and adaptation to illness include the following: the biomedical model which emphasizes disease; psychological models of adaptation to illness; and biopsychosocial models with the latter two emphasizing health, functioning, and well-being. Each of these three major paradigms, including biomedical, psychosocial, and biopsychosocial frameworks, is discussed and critiqued in turn, and contributions and theoretical issues in terms of adjustment to chronic illness, particularly rheumatoid arthritis (RA), are highlighted. Furthermore, a biopsychosocial framework for conceptualizing adjustment to physical illness is proposed that incorporates elements from key existing biomedical and psychosocial models of adaptation to chronic physical health issues.

Abstract
OBJECTIVE The overall effect of rheumatoid arthritis (RA) on general health status has drawn attention in recent years. The aim of this study was to determine the clinical relevance of the Nottingham Health Profile (NHP) in RA patients and the relationship between conventional clinical measures, the Health Assessment Questionnaire (HAQ), and the Beck Depression Inventory (BDI) METHOD: One hundred RA patients (mean age 48.9+/-12.1 years, mean disease duration 101.3+/-85.5 months) were included in the study. Quality of life, health status, and psychological mood of the patients were assessed using NHP, HAQ, and BDI. The Ritchie Articular Index (RAI), visual analog scale, erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), rheumatoid factor, and modified Larsen Scale were used to assess clinical, laboratory, and radiological changes. RESULTS All subgroups of the NHP significantly correlated to VAS, RAI, BDI, and HAQ scores (P<0.001). Except in the social isolation subgroup, there were significant correlations with ESR (P<0.05, P<0.001, and P<0.0001, respectively). There were no correlations between CRP levels and health status measures (P>0.05). CONCLUSION The NHP reflects the clinical and psychological status of RA patients and can be used as a sensitive health status measure for clinical evaluation.

Abstract
The ability to effectively measure health-related quality-of-life longitudinally is central to describing the impacts of disease, treatment, or other insults, including normal aging, upon the patient. Over the last two decades, assessment of patient health status has undergone a dramatic paradigm shift, evolving from a predominant reliance on biochemical and physical measurements, such as erythrocyte sedimentation rate, lipid profiles, or radiographs, to an emphasis upon health outcomes based on the patient's personal appreciation of their illness. The Health Assessment Questionnaire (HAQ), published in 1980, was among the first instruments based on generic, patient-centered dimensions. The HAQ was designed to represent a model of patient-oriented outcome assessment and has played a major role in many diverse areas such as prediction of successful aging, inversion of the therapeutic pyramid in rheumatoid arthritis (RA), quantification of NSAID gastropathy, development of risk factor models for osteoarthrosis, and examination of mortality risks in RA. Evidenced by its use over the past two decades in diverse settings, the HAQ has established itself as a valuable, effective, and sensitive tool for measurement of health status. It is available in more than 60 languages and is supported by a bibliography of more than 500 references. It has increased the credibility and use of validated self-report measurement techniques as a quantifiable set of hard data endpoints and has contributed to a new appreciation of outcome assessment. In this article, information regarding the HAQ's development, content, dissemination and reference sources for its uses, translations, and validations are provided.

Abstract
BACKGROUND Effective treatment of active rheumatoid arthritis (RA) requires early diagnosis and early disease modifying antirheumatic drug (DMARD) treatment to have an impact on long term morbidity and mortality. Clinical criteria would facilitate early referral of the patient with suspected RA to a rheumatologist for definitive diagnosis and initiation of DMARD treatment at that point in the disease most likely to have an impact on the long term outcome. OBJECTIVE To develop a referral recommendation that may serve as a clinical guide for primary care doctors, enabling them to identify patients with suspected RA during the early inflammatory stages. METHODS Key points of the referral criteria were formed based on a thorough literature review targeting early RA, early arthritis clinics, DMARD treatment for early RA, prognostic factors of disease progression, early RA clinical trials, and quality of life. Evidence was graded using the methods defined by Shekelle et al. A draft version of the criterion was circulated among the authors for critical evaluation. A consensus integrated these comments. RESULTS Clinical evidence strongly supports the observations that structural damage occurs early in active RA and that early DMARD treatment improves the long term outcome of the disease. The observations indicate that rapid referral to a rheumatologist is advised when RA is suspected. This may be supported by the presence of any of the following: >or=3 swollen joints, metatarsophalangeal/metacarpophalangeal involvement, and morning stiffness of >or=30 minutes. CONCLUSION The proposed early referral recommendation is a viable tool for primary care doctors to identify potential patients with active RA early in the disease. Early referral to a rheumatologist for definitive diagnosis and early DMARD treatment should improve the long term outcome of RA.

Abstract
OBJECTIVE To determine factors at diagnosis, associated with radiographic damage at diagnosis and after one year, in patients with early rheumatoid arthritis (RA). METHODS New patients with early RA were followed up for one year. Possible prognostic factors were duration of complaints, morning stiffness, disease activity score (DAS28), functional status (Health Assessment Questionnaire (HAQ) score), rheumatoid factor (IgM RF), and C reactive protein (CRP). Outcome was defined as radiographic damage of the hands and feet (Sharp/van der Heijde score). For the statistical analysis, one way analysis of variance and a forward stepwise logistic regression model was used. RESULTS 130 patients with RA (68% female; median age 64 years, range 21-86) were included. Despite the fact that the median duration of complaints was short (15 weeks, range 2-106) the radiographic damage at diagnosis was significantly correlated with the duration of complaints (p<0.05). Patients with a duration of complaints of >34 weeks had significantly more radiographic joint damage at diagnosis than patients with a shorter duration of complaints. Radiographic progression at one year was correlated with high radiographic joint damage, high CRP level, and a positive IgM RF at entry. CONCLUSIONS In early RA, the number of radiographic lesions was correlated with a longer duration of complaints at the first visit. Progression of these lesions was predicted by a high baseline joint damage, high CRP level, and a positive IgM RF. Further reduction of the delay in referral and early treatment may further decrease joint damage in patients with recent onset polyarthritis.

Abstract
OBJECTIVES To investigate the progression of erosions at sites within the carpus, in patients with early rheumatoid arthritis (RA), using magnetic resonance imaging (MRI) and plain radiology over a two year period. METHODS Gadolinium enhanced MRI scans of the dominant wrist were performed in 42 patients with RA at baseline (within six months of symptom onset) and one year. Plain wrist radiographs (x rays) and clinical data were obtained at baseline, one year, and two years. Erosions were scored by two musculoskeletal radiologists on MRI and x ray at 15 sites in the wrist. A patient centred analysis was used to evaluate the prognostic value of a baseline MRI scan. A lesion centred analysis was used to track the progression of individual erosions over two years. RESULTS The baseline MRI erosion score was predictive of x ray erosion score at two years (p=0.004). Patients with a "total MRI score" (erosion, bone oedema, synovitis, and tendonitis) > or =13 at baseline were significantly more likely to develop erosions on x ray at two years (odds ratio 13.4, 95% CI 2.65 to 60.5, p=0.002). Baseline wrist MRI has a sensitivity of 80%, a specificity of 76%, a positive predictive value of 67%, and a high negative predictive value of 86% for the prediction of wrist x ray erosions at two years. A lesion centred analysis, which included erosions scored by one or both radiologists, showed that 84% of baseline MRI erosions were still present at one year. When a more stringent analysis was used which required complete concordance between radiologists, all baseline lesions persisted at one year. The number of MRI erosion sites in each patient increased from 2.1 (SD 2.7) to 5.0 (4.6) (p<0.0001) over the first year of disease. When MRI erosion sites were tracked, 21% and 26% were observed on x ray, one and two years later. A high baseline MRI synovitis score, Ritchie score, and erythrocyte sedimentation rate were predictive of progression of MRI erosions to x ray erosions over one year (p=0.005, 0.01, and 0.03 respectively), but there was no association with the shared epitope. Progression of MRI erosions to x ray erosions was not seen in those with transient polyarthritis. CONCLUSIONS MRI scans of the wrist, taken when patients first present with RA, can predict radiographic erosions at two years. MRI may have a role in the assessment of disease prognosis and selection of patients for more or less aggressive treatment. However, only one in four MRI erosions progresses to an x ray erosion over one year, possibly owing to healing, observer error, or technical limitations of radiography at the carpus. Progression of MRI erosions to x ray erosions is greatest in those with high baseline disease activity.

Abstract
Inflammatory polyarthritis can be a self-limiting disease, develop into rheumatoid arthritis (RA) or differentiate into another form of chronic arthritis. It remains a clinical and scientific challenge to understand the relationship between these phenotypes, determine their aetiologies and predict the course and outcome for individual patients. Even patients labelled as having RA show a wide spectrum of clinical phenotypes. Disease definition is a major problem in studying the aetiology of RA as currently used classification criteria were derived using patients with established disease. RA is thought to result from the combination of genetic susceptibility and exposure to an appropriate environmental trigger. The genetic component is probably oligogenic. The association with HLA has been known for over 25 years. RA is now thought to be associated with a conserved sequence of amino acids in a number of HLA-DRB1 alleles, called the RA shared epitope. However, the shared epitope appears to be associated with RA chronicity and severity more than with susceptibility. Other potential RA susceptibility genes include IL-1, aromatase, corticotropin-releasing hormone and a region on the X chromosome. Hormonal and reproductive factors also influence RA susceptibility and severity. RA is more common in women than men, especially before the menopause. Men may be protected by hormonal factors and require a stronger genetic component to develop disease. Although infectious triggers of RA have long been suspected, no definitive evidence has been obtained. Previous blood transfusion, smoking and obesity are also possible risk factors. Chronicity and remission are important aspects of the natural history of early RA. Although we can identify patients at risk of adverse prognosis with some accuracy, we remain unable to predict remission. Functional disability and radiological damage are the most studied outcomes in RA. Radiological damage often occurs early in the course of RA, but patients may show erosion for the first time several years after symptom onset. Many studies have demonstrated a relationship between HLA and features of severe RA in established patients. This appears to be related to gene dosage.
